There is a 10th planet described by the ancient Sumarians as Nibiru, which orbits between our sun and a twin dwarf sun some 51 light years away. They say its orbit takes some 3600 + years to complete.
Guess what, the astrnomic community has found an object they have called Planet X in Orions belt and it appears to be heading this way. Could this be Nibiru? I checked out some other sites by Googling Nibiru and some of the stuff I read blew my mind! Apparently it is scheduled to enter our solar system and be visable by ordinary telescope by May 15/2009. It will be visable to the naked eye as a red cross by 2011, will orbit our sun 30 degrees above our solar systems elyptical plane and return from below our solar systems elyptical pane heading back out of our solar system. It is expected to come closest to the sun and earth between Dec 21, 2012 and Feb 14, 2013. During which great earthquakes and tidal waves will occur. Add this to what is expected to be worst ever solar sun spot activity recorded and the fact that the sun will experience a polar reversal and we will have a good chance that some really bad is going to happen here on earth!
